The Value Of A Chassis Dynometer



Every automobile performance enthusiast at some point wants to know how much horsepower his or her hotrod has after investing countless hours and dollars in order to make it unique. The easiest and most direct method of acquiring that information is by using a chassis dyno. There are engine dyno’s that measure horsepower at the flywheel. This “flywheel” number is representative of how the O.E.M. manufacturers rate and advertise the performance numbers that you see in magazines, on TV, and in the showroom of your favorite brand of vehicle.  Unfortunately, for the vehicle owner, it’s not practical to remove the engine from an already assembled unit, install it on an engine dynamometer, test it , and then re-install it in the vehicle chassis. Money and time makes it cost prohibitive. It’s just not practical.

The manufacturer however, has the advantage of being able to test the engine assembly before it is
Installed and becomes a finished automobile, ready to drive. The alternative method of acquiring the horsepower number is by installing the vehicle on a chassis dynamometer. It’s a much simpler method because it only requires that the rear wheels to be driven onto the rollers, the vehicle anchored with tie down straps at four corners, attach an electrical pick up lead, and an exhaust gas sniffer hose in the exhaust pipe, and a reference listing of performance upgrades. Once the vehicle has been aligned properly, and the retention straps are tightened, the vehicle is ready for testing. The driving procedure for the chassis dyno is similar to driving on the road except for the fact that you are sitting stationary and only the rear wheels are rotating. Something to keep in mind is that the horsepower value obtained on the chassis dyno will be less than the resulting number obtained on an engine dyno. This lower number is due to the energy absorption requirements to transfer motion from the crankshaft to the rear wheels. This lower horsepower number can easily be adjusted to the flywheel equivalent using a simple formula. Divide the rear wheel HP valve obtained at a drive ratio of 1:1 by .85. This will result in the approximate flywheel HP equivalent.

The industry offers several choices of chassis dynamometers, each of them utilizing their own unique design. The two main engineering types are the inertia dyno and the load dyno. In addition, there are competitive name brands of each type.  In this discussion we will focus on the type or design, not the brand. The two types most commonly used are the inertia dyno and the load dyno. Both designs will measure horsepower at the rear wheels. Each design will provide accurate and repeatable values, but the values are calculated using different engineering designs and therefore the actual  HP “number” recorded by each type will be different , but does that really matter. I will explain…..

Inertia dynos extrapolate horsepower output by analyzing the dyno drum's acceleration rate using a sophisticated accelerometer and computer software. An inertia dyno works only when the car is accelerating. It uses heavy roller drums of known mass mounted on bearings that allow them to freely rotate. A vehicle is placed in position on the dyno with the drive wheels sitting on the rollers. The car is placed in gear and accelerated at wide-open throttle. It takes a certain amount of time and force for the tires to accelerate the heavy rollers. The laws of physics state that acceleration rate is directly proportional to how much power the tires place on the heavy roller to get it to rotate.

The dyno software monitors roller velocity and the time it takes to arrive at a rate of acceleration and estimates power at the rear wheels. Using data from an engine-mounted inductive probe, the software then graphs the power and gear-compensated engine torque against engine rpm. Some inertia dynos also attempt to estimate flywheel power and torque numbers based on mathematical models and data from additional sensors.

A pure inertia-only dyno can only calculate power by measuring the rate of change in acceleration (that's why it's called  an inertia dyno), so it can't do loaded tests or step-tests. The inability to perform load tests makes it difficult to accurately establish optimum timing and fuel curves for use under varying driving conditions. On today's inertial dynos, the static roller weight or resistance isn't adjustable to match vehicle weight; depending on the dyno software and whether the  inertial test function can be combined with a strain gauge to effectively change the rollers' inertia trim-as is possible on higher-end multifunction dynos-extremely light or heavy vehicles might fall off the curve, and turbocharged engines won't build boost as they do in the real world. On the other hand, with mainstream vehicles weighing around 3,500 pounds, the results are repeatable with minimal setup time. Dynojet is the most common pure-inertia dyno in use today; however, some of its newer models also have an eddy-current option. Load dyno’s, also known as an eddy-current dyno. This type of dyno controls the brake/absorber using electric current instead of fluid, measuring torque output and calculating horsepower based on a strain-gauge. Electric current provides much more
precise control and minimal spool-up lag-time, but you need a gonzo electric supply and the dyno itself is more expensive than other types. Top-flight eddy-current dynos are used for sophisticated R&D and emissions testing where dead-nuts accuracy is extremely important. They are especially useful in calibrating electronic engine-management systems at varying vehicle loads.
On the other hand, utilizing the capabilities of this dyno to its full potential requires a high degree of skill and setup time. Mustang and SuperFlow are among those companies marketing high-end eddy-current dynos. Some eddy-current dynos can also be run in "pure inertia mode," but then they have the same drawbacks as any other pure inertia dyno. Many factors that influence test accuracy are common to all dynos, including engine dynos; these include temperature, airflow, barometric pressure, and torque calibration. But on chassis dynos, many additional factors can affect the results,
factors much harder to control than those typically encountered on an engine dyno. Drivetrain losses vary according to gear selection (testing should usually be performed in the transmission's 1:1 gear to minimize this factor), fluid temperatures, acceleration/ load factors, drivetrain inertia, brake drag, the vehicle tie-down method, the weight over the axle, and tire selection, growth, and slippage.

The bottom line, and the most important point of fact, is that no matter what type of dyno you choose to use, it is the before and after NET result that matters. What you gain in performance from the money you’ve spent and the changes that you have made. The actual HP number is just for bragging, bench racing, and impressing your competitors.
